HCID 13662N-Phenylmaleimide

Procedure

Aniline, a primary aromatic amine, is a hazardous carcinogenic liquid. It is difficult to handle aniline safely during reactive extrusion, which is the most economical way to produce imides on a large scale. Often maleic anhydride is reacted with aniline to obtain the N-phenylmaleimide monomer, which is then copolymerized with other monomers in solution or emulsion polymerization processes.
